Suppose that 14 children, who were learning to ride two-wheel bikes, were surveyed to determine how long they had to use training wheels. It was revealed that they used them an average of nine months with a sample standard deviation of two months. Assume that the underlying population distribution is normal.Subpart ## Part (e)**Construct a 99% confidence interval for the population mean length of time using training wheels.**### (i) State the confidence interval. (Round your answers to two decimal places.)( _______ , _______ )### (ii) Sketch the graph. (Round your answers to two decimal places. Enter your α/2 to three decimal places.)- The graph shown is a bell-shaped curve representing a normal distribution. - The central region is shaded with "CL =" indicating the confidence level, which is 99% for this problem. - The tails of the distribution have sections marked as "α/2 =".- The horizontal axis shows a point labeled as \(\bar{x}\), representing the sample mean. - There are three unlabeled tick marks on the axis, presumably for indicating the bounds of the confidence interval and the sample mean.### (iii) Calculate the error bound.(Round your answer to two decimal places.)_______
